OEM Carrier Flame Sensor Assembly LH33WZ005 for Model PY1PPA060120ADBA

This OEM Carrier flame sensor assembly is the factory-specified replacement for the Carrier PY1PPA060120ADBA packaged gas/electric unit. The flame sensor — also called a flame rod or rectification sensor — monitors the burner flame by passing a small electrical current through the flame to ground. When it detects a valid flame signal, it tells the control board to keep the gas valve open. When the sensor fails due to carbon buildup, corrosion, or a cracked ceramic insulator, the unit will ignite normally but shut down after just 5–8 seconds, triggering a lockout fault code. The result: no heat despite repeated ignition attempts.

• OEM Part Number: LH33WZ005 | Carrier Factory Authorized Part | 64.5" wire lead | Flame rod with ceramic insulator and bracket mount
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact rectification specifications. Aftermarket sensors often have mismatched rod geometry or inferior ceramic insulators that degrade faster and produce weaker microamp signals, causing nuisance shutdowns and accelerated control board wear.
• Install Difficulty: 2/5 — Turn off gas and power before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Photograph existing wire routing before removal. Clean the burner port area before installing the new sensor. Do not touch the flame rod with bare hands — skin oils shorten sensor life.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3PM local time.
